Answer» Step-by-step explanation: 1) In first condition we have to prove that both the TRAINGLES are similar. So, for that we need to prove that all the respective angles of both the triangles are equal. here, in triangle ACD and ABD. angle D = angle D (both 90°) 2) For finding the length of AD we have a formula of drawing an altitude on the hypoteneuse which is, Altitude of hypoteneuse h×h = x × y here x and y are the segments in which altitude divides the hypoteneuse and here x is 8 and y is 18 so, AD => h^2 = 8 × 18 => h = / 8 × 18 => h = 4 × 3 => h = 12cms. 3) ratio of the area of any 2 similar triangle is SQUARE of the ratio of their corresponding sides. here ratio of CD and BD is, CD/BD = 8/18 CD/BD = 4/9 SO, now square of these two will be, Area of CDA : AREA OF ABD = 16 : 81 HOPE THIS WILL HELP.

|
Answer» Answer: Step-by-step explanation: CURVED Surface area of a frustum of a cone =πl(r 1 +r 2 ) where l is the slant height, r 1 and r 1 are the RADII of the lower and upper ends of a frustum of a cone. Circumference of the lower circular base =2π r 1 =18 ⇒r 1 = π 9 cm Circumference of the upper circular base =2π r 2 =6 ⇒r 2 = π 6 cm GIVEN, curved Surface area of the frustum of a cone =π×l×( π 9 + π 6 )=180 l=15 cm |

Pls answerAB is tangent to both circlesfind angle ACB + angle ADB |
|
Answer» Step-by-step explanation: WE are GIVEN that the two circles intersect each other at C and D and the line ab is the common tangent, then ANGLE made by the chord and tangent= angle in alternate SEGMENT, therefore ∠CBA=∠CDB and ∠CAB=∠CDA. Now, as ∠CDB+∠CDA=∠CBA+∠CAB ⇒∠ADB=180°-∠ACB ( because from the FIGURE it is given that ∠CDB+∠CDA=∠ADB) ⇒∠ADB+∠ACB=180° Hence proved. |

If the speed of aroplane is decreasedby 120km/h it takes 18 minutes more to travel some distance if the speed is increased by180 km/h it takes 18 minute less to travel thesame distene find the average speed of thecreepend thece |
|
Answer» If the average SPEED decreases by 120 km/hr & the time increase by 18 MIN and if the speed is INCREASED by 180 km/hr & the time reduces by 18 mins then the average speed of the car is 720 km/hr and the distance travelled is 1080 km. Step-by-step explanation: Required formula: Average Speed = Let the average speed of the aeroplane be denoted by “x” km/hr and the distance travelled by it be denoted by “y” km/hr. Step 1: According to the first condition given in the question and based on the above formula, we can write the eq. as, ⇒ …… (i) According to the second condition given in the question and based on the above formula, we can write the eq. as, ⇒ …… (ii) Step 2: On dividing the eq. (i) by (ii), we get = ⇒ = ⇒ = ⇒ 120 (x+180) = 180 (x-120) ⇒ 2x + 360 = 3x - 360 ⇒ x = 720 km/hr Step 3: Substituting the value of x = 720 km/hr in eq. (i), we get y [] = ⇒ y [] = ⇒ y [] = ⇒ y = * (720*600) * ⇒ y = 1080 km Thus, the average speed of the car is 720 km/hr and the distance travelled by it is 1080 km.
